2 Claims.

This invention relates to new and useful improvements in a roller guard to be used principally in conjunction with laundry clothes wringing machines. Its primary object being to prevent clothes from sticking to the rollers and becoming wound around on the same before the machine can be stopped.

A further object of the invention is to provide a roller guard that will engage the rollers under slight spring pressure and prevent the clothes adhering thereto beyond the point of contact between the said guard and said roller.

A still further object of the invention is to devise a roller guard that will prevent clothes winding on the said roller, will assist in keeping the rollers clean and to facilitate the wringing of fabrics in a shorter time and thereby adapting the machine to better perform the functions required of it.

With these and other objects in view that may appear while the description proceeds, the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming part of this application and in which:

Fig. 1 is a general elevation of the upper roller and pressure means of a typical wringing machine.

Fig. 2 is a diagrammatic end elevation showing the upper and lower roller guards.

Fig. 3 is a partial plan view of the upper roller guard.

Fig. 4 is a sectional view of one blade showing the preferred shape thereof. V

Fig. 5 is an enlarged sectional view of the upper roller guard means.

Referring more in detail to the drawing in which similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises upper and lower rollers 10 and I l rotatably supported in the wringer frame in the usual manner by the pressure bearing blocks I2.

The upper guard l3 comprises two blades l4 positioned one on either side of the roller 10. These blades are joined together and to a longitudinal support strip l5 by lateral members l6. These are preferably of spring steel to give the required tension of the blade on the roller and may be spot welded to the blade and to the sup- I port strip I5.

The assembled upper guard I3 is positioned above the roller and the ends ll of the support member rest on the pressure blocks I2. The

1935, Serial No. 11,138

pressure spring I8 engages the same and. holds the device firmly in position whenpressure is applied by the pressure screw IS. The depth of the blades is preferably sufficient so that the top thereof will be under the spring casing to present a more pleasing appearance, and also to prevent dirt or any foreign matter getting behind the same.

The lower roller guard comprises two blades 2| and 22 which are secured to the water diverting tray 23, which is standard equipment on the wringing machines, by means of lateral springs 24 which may be spot welded to the blades and riveted to the tray or secured in any convenient manner depending on the material used for the various parts.

The water diverting tray is pivoted in the frame in a manner to divert the Water either Way depending on the direction of the feed. As shown in Fig. 2 the pivotal movement of the tray brings one or the other of the blades into contact with a light spring tension with the roller I l and consequently the opposite blade is disengaged there-' from. The cross-sectional shape of the blades shown in Fig. 4 discloses a longitudinal ridge 25 which diverts the clothes or fabrics from the blade and breaks any suction which may be created therebetween.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawing without further detailed description.

While the preferred embodiments of the invention have been disclosed it is understood that minor changes in the details of construction, combination and. arrangement of cooperating parts may be resorted to within the scope of What is claimed without departing from the spirit of the invention.

We claim:

1. A guard for wringer machine rollers comprising a longitudinal strip having its ends mounted in the frame of the wringer, and disposed in superimposed spaced relation to the roller, means for exerting a downward pressure on said strip, transverse spring strips connected to said longitudinal strip at spaced intervals and extending beyond the edges thereof, and stripping blades connected to the ends of said transverse strips and depending therefrom in parallel relation, said blades being disposed in a vertical plane within the diameter of the roller with their lower edges in resilient contact with the surface of the roller.

2. A guard for wringer machine rollers comprising a longitudinal strip having its ends mounted in the frame of the wringer and disposed in superimposed spaced relation to the roller, means for exerting a downward pressure on said strip, transverse spring strips connected to said longitudinal strip at spaced intervals and extending beyond the edges thereof, stripping blades connected to the ends of said transverse strips and depending therefrom in parallel relation, said blades being disposed in a vertical plane within the diameter of the roller with their lower edges in resilient contact with the surface of the roller, and a longitudinal ridge extending out- Wardly from said blades near their lower edges.
